We have a single Exchange 2007 Server in our Domain.
We are adding another remote office with approx 30 users - So we have decided to deploy a second Exchange 2007 Server.
This second Server will also be the remote sites Domain Controller / File share server.
We have a DMZ Mail Server (MailMarshal SMTP ) processing incoming and outgoing mail at head office.
The remote office will be connected back to head office over two IPSEC VPNs , one VPN for Client network access (SSH Oracle application, some shares and Citrix apps - all located at head office) and the other for Server to Server communication (Exchange , Active directory... and so on).
My question is more about how to add the additonal Exchange Server (exchange 2007 seems very different to 2003)
Add exchange 2007 to the remote site
Do I then forward mail directly from the DMZ SMTP to the second Exchange server for those remote users or should it go through to the first exchange server and then be processed to the second exchange server?
Any help in setting this up would be great.
Basically we just want the remote site to be able to send internet mail straight out through their internet connection, and to receive company email from either the DMZ SMTP or the head office exchange server.
